Problems solved by technology

However, as a textile fiber, it also has many defects: the strength of viscose fiber is low, especially the wet strength, which is usually only about one-half of the dry strength; the fabric made of viscose fiber cannot be scrubbed strongly when washing, and the service life is short The shrinkage rate of viscose fiber is high, and the appearance of the fabric after washing is not ideal; the elasticity of viscose fiber is poor, and it is easy to deform when worn, causing wrinkles, which affects the appearance of the fabric
But the cost of this method is extremely high, because the price of graphene is hundreds of yuan to thousands of yuan per gram, making it difficult to promote on a large scale

Abstract

The invention discloses a process for improving the wear resistance, breaking strength and elasticity of viscose fibers, improving the dimensional stability of viscose fiber products and relieving thecrease degree of the viscose fiber products by adding conventional fillers and modified fillers into viscose. The added conventional fillers can effectively improve the wear resistance, breaking strength and elasticity of the viscose fibers; the wear resistance, breaking strength and elasticity of the viscose fibers can be further improved by using hydroxyl cellulose coupling; a small amount of hydroxyl-terminated silicone oil is coupled to further reduce the friction coefficient of the surface of the viscose fibers and improve the wear resistance of the viscose fibers. The viscose fibers areused as a raw material, thus the wear-resistant improved viscose composite yarn can be prepared through a blowing, carding, drawing, roving, spinning and spooling process, the viscose composite yarnhas the advantages of being good in wear resistance, high in breaking strength and good in elasticity, and the dimensional stability and crease resistance of a viscose fiber fabric can be effectivelyimproved.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a wear-resistant improved viscose composite yarn and a preparation method thereof. Background technique [0002] Viscose fiber is mainly made of natural cellulose such as cotton linters, wood and a small amount of bamboo. After a series of processing processes such as cooking and bleaching, it is made into dissolving pulp with high purity of cellulose, and then soaked and pressed. , crushing, aging, yellowing, dissolving, mixing, filtering, defoaming, filtering, spinning, post-processing, drying, packaging and other processes. At present, it is mostly used as textile fiber. Ordinary viscose fiber has excellent wearing performance, which is very similar to some properties of natural cotton fiber. It has good hygroscopicity, dyeability, antistatic, comfortable to wear, and has advantages that other chemical fibers cannot match. However, as a textile fiber, it also has...
